AI agents working inside a real Page Object Model instead of writing throwaway scripts: a planner explores the app, a generator writes the test, a healer repairs failures from traces — all running against the login practice page on this site.
Beginner-friendly Page Object Model starter: base page class, encapsulated locators, business-level methods, and a GitHub Actions workflow.
Runnable examples for locators, assertions, API testing, network interception, codegen, accessibility checks, and visual comparisons.
A JavaScript automation framework built step by step — the practical companion to the Playwright course.
Python fundamentals and testing resources for QA engineers moving beyond JavaScript.
